Description

Technical Field

[0001] This utility model belongs to the field of sterilization equipment technology, specifically relating to a water treatment sterilization device. Background Technology

[0002] With the increasing severity of global water pollution, existing water treatment and sterilization technologies face challenges such as the hazards of chemical disinfection byproducts and the inability of physical filtration to completely kill bacteria. Meanwhile, ultraviolet (UV) sterilization is gaining attention due to its advantages such as high efficiency and no chemical residues.

[0003] Existing water treatment sterilization equipment typically installs ultraviolet lamps inside the equipment, near the water inlet, to sterilize the water flow at the inlet. This results in a limited sterilization range for the ultraviolet lamps, which often only sterilize the water flow near the inlet. When the water flow rate is high, the water flow will quickly leave the sterilization range of the ultraviolet lamps, resulting in poor sterilization effect of the ultraviolet lamps on the water flow.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] In one embodiment, reference is made to Figures 1 to 4As shown, this embodiment provides a water treatment sterilization device, which includes an outer tube 1, an inner tube 2, and an ultraviolet lamp assembly 3. The outer tube 1 has a chamber inside, and an inlet 11 and an outlet 12 communicating with the chamber. The inner tube 2 is fitted inside the chamber of the outer tube 1, and a water flow channel 21 communicating with the inlet 11 and the outlet 12 is formed inside the inner tube 2. A reflective surface 22 is formed on the inner surface of the inner tube 2. The ultraviolet lamp assembly 3 is at least partially installed inside the chamber, with at least a portion of its light-emitting side facing the water flow channel 21, used to irradiate ultraviolet light onto the reflective surface 22. The ultraviolet light is continuously reflected within the water flow channel 21, eventually diffusing to various areas of the water flow channel 21, sterilizing the water flow within the water flow channel 21, expanding the sterilization range of the ultraviolet lamp assembly 3, and improving the sterilization effect of the ultraviolet lamp assembly 3 on the water flow.

[0027] In one embodiment, reference is made to Figure 2 and Figure 3 As shown, the outer tube 1, inner tube 2, and ultraviolet lamp assembly 3 are roughly arranged on the same straight line. In order to facilitate the water flow into the water flow channel 21, the inlet 11 is formed on the peripheral wall of the outer tube 1. The central axis of the inlet 11 is roughly perpendicular to the central axis of the outer tube 1. The peripheral wall of the inner tube 2 has a flow port 23 connected to the inlet 11. The central axis of the flow port 23 is roughly perpendicular to the central axis of the inner tube 2. The pipe opening of the inner tube 2 near the inlet 11 is sealed with the light-emitting side of the ultraviolet lamp assembly 3 to close the pipe opening of the inner tube 2 near the ultraviolet lamp assembly 3.

[0028] The opening of the inner tube 2 and the light-emitting side of the ultraviolet lamp assembly 3 can be sealed by simply abutting each other, or a sealing ring or other sealing element can be installed at the contact point between the two.

[0029] Furthermore, the light-emitting side of the ultraviolet lamp assembly 3 extends into the water flow channel 21 to close the opening of the inner tube 2 and reduce the distance between the reflective surface 22 and the ultraviolet lamp assembly 3, so that more ultraviolet light can irradiate the reflective surface 22.

[0030] In other alternative embodiments, the light-emitting side of the ultraviolet lamp assembly 3 can also extend entirely into the water flow channel 21, which can minimize the exposure of ultraviolet light to the outer area of ​​the water flow channel 21 and further improve the utilization rate of ultraviolet light.

[0031] In addition, it should be understood that the part of the ultraviolet lamp assembly 3 that can emit ultraviolet light should be regarded as the light-emitting side of the ultraviolet lamp assembly 3.

[0032] In one embodiment, reference is made to Figures 2 to 4As shown, the inner tube 2 is inserted into the chamber through the mounting port 15 at the end of the outer tube 1. To facilitate the quick insertion of the inner tube 2 into the chamber of the outer tube 1, the inner diameter of the chamber is designed to gradually decrease. Specifically, the inner diameter of the chamber gradually decreases in the direction away from the mounting port 15 of the outer tube 1, and the outer diameter of each part of the inner tube 2 remains approximately the same and does not exceed the minimum inner diameter of the chamber.

[0033] According to the above structural design, the inner diameter of the outer tube 1 is not completely matched with the outer diameter of the inner tube 2. The gap between the inner surface of the outer tube 1 and the outer surface of the inner tube 2 forms a flow gap 13. The flow gap 13 is connected to the inlet 11 of the outer tube 1 and the outlet 23 of the inner tube 2. The flow gap 13 extends to the area between the inner surface of the outer tube 1 and the outer surface of the light-emitting side of the ultraviolet lamp assembly 3. Part of the ultraviolet light emitted by the ultraviolet lamp assembly 3 can irradiate into the flow gap 13 to sterilize the water flow in the flow gap 13.

[0034] In addition, when the outer tube 1 is formed by injection molding, the gradually narrowing inner diameter of the outer tube 1 is also beneficial for demolding after the outer tube 1 is formed.

[0035] Furthermore, multiple flow ports 23 are formed on the inner pipe 2 along its circumference. The multiple flow ports 23 are simultaneously connected to the flow gap 13 so that the water in the flow gap 13 can quickly flow into the water channel 21 after sterilization, avoid the formation of flow dead zones in the flow gap 13 and prevent the water from accumulating in the flow gap 13 for a long time.

[0036] Multiple flow ports 23 can be roughly distributed on the same cross-section of the inner tube 2, or they can be set on different cross-sections of the inner tube 2 according to the flow rate in different regions of the flow gap 13. The inner diameters of the multiple flow ports 23 can be the same, or they can be differentiated according to the flow rate in different regions of the flow gap 13. The multiple flow ports 23 can be evenly spaced, or the spacing of the flow ports 23 can be differentiated according to the flow rate in different regions of the flow gap 13.

[0037] In one embodiment, reference is made to Figures 2 to 4 As shown, a first sealing ring 4 is fitted on the outer surface of the inner tube 2. The first sealing ring 4 is located on the side of the flow port 23 away from the ultraviolet lamp assembly 3. The first sealing ring 4 is sealed with the inner circumferential surface of the outer tube 1 and the outer circumferential surface of the inner tube 2, dividing the flow gap 13 into two essentially non-connected parts. One part of the flow gap 13 is relatively close to the ultraviolet lamp assembly 3, and the water flow in this part can be directly or indirectly irradiated by ultraviolet light. The other part of the flow gap 13 is relatively far away from the ultraviolet lamp assembly 3, and the sterilization effect of ultraviolet light on the water flow in this part is poor. Therefore, the first sealing ring 4 can prevent unsterilized water flow from entering this part of the flow gap 13.

[0038] In one embodiment, reference is made to Figures 2 to 4 As shown, a radially protruding rib 14 is formed inside the outer tube 1. The rib 14 can be generally constructed as a plate-like structure or a block-like structure. The rib 14 is arranged opposite to the mounting port 15. After the inner tube 2 is inserted into the cavity of the outer tube 1 through the mounting port 15, the end of the inner tube 2 away from the mounting port 15 is supported by the rib 14 along the axial direction of the inner tube 2. The rib 14 enhances the structural strength of the outer tube 1 at the end away from the mounting port 15, and prevents the outer tube 1 from deforming, cracking or other structural damage under the long-term support of the inner tube 2.

[0039] Furthermore, multiple ribs 14 can be provided, and the multiple ribs 14 are distributed at equal intervals.

[0040] In other alternative embodiments, it is also possible to remove the rib 14 and make the end wall thickness of the outer tube 1 away from the mounting port 15 thicker, which can also enhance the structural strength of the outer tube 1.

[0041] In one embodiment, reference is made to Figures 1 to 4 As shown, the UV lamp assembly 3 includes a cover 31, a lampshade 32, and a UV lamp 33. The cover 31 is sealed to the mounting port 15 of the outer tube 1, specifically through a sealing component such as an adhesive. The lampshade 32 is mounted on the cover 31, specifically on the inner side of the cover 31, i.e., the side of the cover 31 facing the inner tube 2. The UV lamp 33 is mounted inside the lampshade 32, and a second sealing ring 5 is also installed inside the lampshade 32. The second sealing ring 5 isolates the space inside the lampshade 32 from the space outside the lampshade 32, preventing water from entering the lampshade 32.

[0042] Furthermore, the UV lamp assembly 3 also includes a cable 34 that connects to and powers the UV lamp 33. One end of the cable 34 extends into the outer tube 1 and connects to the UV lamp 33, while the other end extends out from the inside of the outer tube 1.

[0043] Furthermore, to strengthen the connection between the cover 31 and the outer tube 1 and to prevent the cover 31 from loosening after prolonged use, the cover 31 is also connected to the outer tube 1 by bolts 35.

[0044] In one embodiment, the inner tube 2 is made of a reflective material, including but not limited to stainless steel, aluminum, high-reflectivity polymers, and glass and ceramic materials with silver or aluminum plating on the inner wall.

[0045] In another embodiment, only the inner surface of the inner tube 2 is made of reflective material. Specifically, the inner tube 2 can be made of materials such as polytetrafluoroethylene. Then, reflective material is coated on the inner wall of the inner tube 2 to form a reflective layer on the inner wall of the inner tube 2. At this time, the surface of the reflective layer can be regarded as the reflective surface 22 of the inner tube 2.

[0046] In one embodiment, the entire inner surface of the inner tube 2 forms a reflective surface 22, ensuring that the reflective surface 22 is distributed in each area of ​​the water flow channel 21.

[0047] In another embodiment, a portion of the inner surface of the inner tube 2 forms a reflective surface 22. As an example, the reflective surface 22 may be formed only in the area of ​​the inner surface of the inner tube 2 that is relatively close to the ultraviolet lamp 33.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
